Author's category · 12 items
1. 1
  Melee Lifesteal
  ALWAYS a first buy!!! Proc it with your 2 and sell later for slot... Lets you out-trade enemies with damage + healing (use ur weapon !!!), making you very hard to kill with Ava’s 15 regen
2. 2
  Stalker
  free dmg and movespeed
3. 3
  Close Quarters
  play at close range and trade damage with melee lifesteal (use the item!!!)
4. 4
  Sprint Boots
  good for early game boxing / rotations
5. 5
  Extended Magazine
  With how much fire rate we’re building, you’ll need this
6. 6
  Swift Striker
  Fire rate and sprintspeed (can't ask for more)
7. 7
  Enduring Speed
  Built from Sprint Boots
  Ava and her ult scale with move speed, and it gives instant value. Better roaming, ult stickiness, faster escapes + slow resist
8. 8
  Fleetfoot
  Can’t ask for more. Cast it on ult/Cat Form for extra speed, slide more = Infinite Ammo, and get slow resist + no shooting penalty. Perfect for close-range fights, chasing, box runs & rotations
9. 9
  Dispel Magic
  vs. debuffs / can be clutch if they’re countering you
10. 10
  Titanic Magazine
  Built from Extended Magazine
  With how much fire rate we’re building, you’ll need this
11. 11
  Hunter's Aura
  less bullet resist and fire rate... Great for isolated fights and helping with camps & objectives
12. 12
  Burst Fire

  Rebuttal
  Can be clutch in some matchups
2. 2
  Extra Health
  Buy it early if you need sustain / if you’re in a hard lane
3. 3
  Healbane
  You really don’t wanna buy this, but if nobody on your team is getting anti-heal, just go for it. You’ll proc it with your combo anyway, and even on gun build, you still wanna engage with your combo

  Bullet Lifesteal
  Can be bought after Glass Cannon... gives good sustain

  Best item for gun calico, but if you think you can't stack it, take lucky shot instead
3. 3
  Split Shot
  Pair it with Vamp and you’re basically immortal
4optional

  Unstoppable
  vs cc
3. 3
  Silencer
  vs. annoying spirit heroes
